It's been 3-1/2 years plus since we first became acquainted with Jeff Werthman at Grand Shipper. As such, I can't help but say that Jeff has been one of the best customer care professionals, most courteous, most compassionate, most competent, and responsive individuals that I have ever experienced in this industry.

Deborah Durr

Grandshipper is ideal for new business owners. My business is new and the expertise that I experienced is recommended to all that may have issues setting up a shipping solution and connecting it to a website. I have a Wix website and Grandshipper supports WIX.

Grandshipper has been a game-changer for us—saving both time and money on our shipping needs. From day one of reaching out, Jeff has been especially helpful, knowledgeable and always quick to respond. Highly recommend working with them!

Lindsey Diener

We needed a solution fast! With minimal knowledge of shipping beyond a few packages from time to time, GrandShipper came through! Jeff was super helpful and easily communicated options and helped guide towards the best solution for our needs. Shout out to Jay who hopped on a last minute call to walk me through through the whole process! Great customer service and a knowledgeable team!

Joan Eckstein

GrandShipper Customer Service came quickly to my rescue after sending an email to "Contact Us!" And they didn't give up on me until my question was answered! Thank you, GrandShipper! ILY!

Amazing experience!! The service is great and swift.

Annette Hall

Working through Grandshipper to mail our packages instead of going directly through the Post Office has saved our non profit organization both money and time. The post office would have our priority mail boxes sitting for days while processing each one and with Grandshipper and using the prepaid labels and manifest our packages go out the same day they are delivered to the post office AND we save money on each package over the post office rates. Special Thanks to Jeff who is easy to work with and always patient with my questions. I definitely recommend Grandshipper to help your business and non profit save both time and money.
